HPI Racing Baja 5B 2.0 Version 115891 Exploded View

To break in the engine, start by using a high-quality 2-stroke oil mixed at a ratio of 25:1. Run the engine at idle for one full tank of gas, allowing cooling periods between runs. Gradually increase the throttle over the next few tanks.
Regular maintenance includes checking and cleaning the air filter after every run, inspecting the suspension for wear, tightening screws and nuts, and lubricating moving parts. Perform a full inspection every 5-10 runs.
Adjust the suspension settings by changing the shock oils and springs based on the terrain. Use softer settings for rough terrain and harder settings for smooth surfaces. Tire selection also plays a crucial role.
Check the spark plug for fouling and replace if necessary. Ensure the fuel is fresh and the carburetor is not clogged. Check for proper compression and inspect the ignition system.
Begin with the factory settings and make small adjustments to the high-speed and low-speed needles. Tune the engine for smooth acceleration and a steady idle, ensuring not to lean the mixture excessively.
Consider upgrading to aluminum parts for areas prone to impact, such as A-arms and shock towers. Reinforced shock shafts and heavy-duty drive shafts can also improve durability.
Clean the vehicle thoroughly and remove any fuel from the tank. Store it in a cool, dry place, and consider applying a light coat of oil to metal parts to prevent rust. Disconnect the battery to avoid drainage.
Common issues include stripped gears and slipping clutches. Regularly inspect and replace worn gears, and adjust the clutch spring tension as needed to ensure proper engagement.
Use high-capacity batteries and charge them fully before use. Avoid over-discharging and store them at a proper storage voltage. Regularly balance charge your LiPo batteries.
Always operate in a safe, open area away from people and animals. Wear protective gear such as gloves and goggles, and keep a fire extinguisher handy due to the flammable nature of the fuel.
